C2 QUAD PROTECTOR

DISPLAY AND ALARM CONTROLLER

The GDS Corp. C2 Quad Four Channel Display / Alarm Controller is designed to provide simultaneous display and alarm functions for four gas detection variables. A graphic LCD displays monitored data as bar graphs and engineering units. Three adjustable alarm levels are provided per channel. Relay outputs allow control of beacons, horns and other alarm events.

The C2 Quad Protector controller supports industry standard 4-20mA inputs as well as direct connection to catalytic bead or SmartIR infrared sensors for combustible gases or photoionization (PID) sensors for Benzene or other volatile organic compounds (VOCs). Sensors may be remote mounted. When using the direct bridge input option, up to two of the four channels can be configured for direct 4-20mA analog input.

The C2 Quad is easy to configure and user friendly. Measurement ranges in engineering units, adjustable alarm set-points, optional serial interfaces, and many other features offer flexibility to meet most demanding applications.

An optional RS-485 Modbus slave port allows up to 128 C2's to be multidropped onto a single data highway for interrogation by a remote MODBUS master device. A MODBUS TCP interface is also available for ethernet network applications.

Available C2 Quad options include 5 amp SPDT discrete alarm relays per channel, 4-20mA outputs, light stacks and audible annunciators.
